vectors

Can anybody show me how to create a simple vector containing a list of people with their first names, last names, and phone number, with a constructor??
the only way i can create it, is by implementing a structure .
How ever, I read in some article that it is possible to do it without structure. and I am a little bit confused by that

struct MyContact
{
    MyContact(const std::string &first, const std::string &last, const std::string &phone_num) : 
        first_name(first), 
        last_name(last), 
        phone_number(phone_num)
    {
    }

    std::string first_name;
    std::string last_name;
    std::string phone_number;
};

std::vector<MyContact> contact_list;

I still don't see how come i can initialize many contacts in this vector?
is it considered as an array ?

So this is how you use it :

std::string first;
std::string last;
std::string phone_num;

int i;
int N = 10;
for(i = 0; i < N; i++)
{
    cout << "Enter first name : "; cin >> first;
    cout << "Enter last name : "; cin >> last;
    cout << "Enter phone number : "; cin >> phone_num;

    contact_list.push_back(MyContact(first, last, phone_num));
}
